Break Planner

---
name: break-math
description: Pricing and paperwork for sports card and trading card breaks (group breaks, case breaks, pick-your-team, pick-your-spot and random team breaks). Works out spot prices from the breaker's product cost, demand weights, platform fees, shipping, other costs and target margin; profit if every spot sells; the breakeven and how many spots cover it; a pre-break run sheet; and a hit-by-hit recap for buyers. Use when the user says things like "price my break", "how much should each team cost", "what do I need to charge to break even on this case", "random team price", "make a break recap", or is planning or wrapping up a break. It uses only the user's numbers and doesn't give legal advice on breaks.
